Date Section Pages etc Mr Richter Agenda Today Warm Up Review HW from 71 Practice Problems for 72 Intro to Collisions 73 Tomorrow Conservation of Momentum Lab Thursday Review HW from 72. http://. www.aplusphysics.com. /courses/honors/momentum/. collisions.html. Unit #4 Momentum. Objectives and Learning Targets. Define and calculate the momentum of an object.. Determine the impulse given to an object.. What couldn’t you live without?. Price Elasticity. Price. Quantity. You will pay anything to drink….Which is why Governments control water supplies…Price inelastic!. Price Elasticity. Price. Quantity. & Energy in Collisions. Given some information, & using conservation laws, we can determine a . LOT. about collisions without knowing the collision forces! To analyze . ALL. collisions:. . Get a Whiteboard and a Dry Erase Maker so we can Practice.. Using your whiteboard, draw the following:. Draw the demand curve for . Coca-cola. the market.. Show what will happen to the market if Coke goes on sale.. Completely elastic collision. If . all. of the kinetic energy is conserved, the collision is . completely elastic.. Completely inelastic collision. If the objects . stick together. , the collision is . Bell Ringer. A . 40 kg . miniature horse runs west at . 8m/s. . What is the force . of impact if it hits a wall and . comes to a stop . in . 0.5s. ?. Objectives. We will . demonstrate . and apply the laws of . Inelastic vs. Elastic. Pg. 233 – 239. Pg. 240 - 248. Momentum vs. Energy. All interactions conserve momentum.. They do . not necessarily. conserve kinetic energy.. Obvious example: Explosions. Kinetic energy before is zero.. Contents:. Quandary. Elastic vs inelastic. Demos. Quandary. Before. v = 560 m/s. m = 100. grams. Block O . Wood. v = 0 m/s. m = 845 grams. After. Bullet. and. Block combo. v = ???. Calculate:. Velocity after. University of Michigan. Physics Department. Mechanics and Sound . Intro . Labs. Two-Dimensional Collisions. You have now seen the laws of conservation of momentum and energy in action in one-dimensional collisions, and you have begun to explore rotational motion. Now it is time for you to apply these concepts to a two-dimensional situation.. The truth about …. The only way to tell …. … whether a collision is elastic or inelastic is to find out whether . kinetic energy . is conserved or not.. You have to calculate the kinetic energy before and after the collision.. & Energy in Collisions. Given some information, & using conservation laws, we can determine a . LOT. about collisions without knowing the collision forces! To analyze . ALL. collisions:. . Corina. . Bot. , PhD (NJIT, C. 2. PRISM). Keri . Salvador (NJIT, C. 2. PRISM). Caroline . Savio. (ESHS, NPS). Career Day. May 11. th. , . 2010. Outline of Presentation. About Collision Course Applet. Law of Conservation of Momentum. With no external force, momentum doesn’t change. It’s the opposite of the impulse momentum relationship!. Ft = Δmv. Example. Consider a gun being fired.. A gun recoils when it is fired. . THE LAW OF DEMAND TELLS US:. When price increases, the QUANTITY demanded decreases, and when prices decrease, the QUANTITY demanded increases.. Why does the . Qd. change?. Consider what happens when Oakland apartment rents increase:.
